The length of the hypotenuse of a right triangle is 20 feet. The tangent of one of the acute angles, angle 0, is 1.42. What is t
larisa86 [58]

Answer:

16.4 feet.

Step-by-step explanation:

We have been given that the length of the hypotenuse of a right triangle is 20 feet. The tangent of one of the acute angles, angle \theta, is 1.42. We are asked to find the length of the side opposite angle \theta.

We can represent our given information in an equation as:

\text{tan}(\theta)=1.42

Now, we will use arctan to solve for theta as:

\theta=\text{tan}^{-1}(1.42)

\theta=54.85^{\circ}

Now, we will use sine to solve for opposite side as sine relates opposite side of right triangle with hypotenuse.

\text{sin}=\frac{\text{Opposite}}{\text{hypotenuse}}

\text{sin}(54.85^{\circ})=\frac{\text{Opposite}}{20}

20\cdot \text{sin}(54.85^{\circ})=\text{Opposite}

20\cdot 0.81764=\text{Opposite}

\text{Opposite}=20\cdot 0.81764

\text{Opposite}=16.3528

\text{Opposite}=16.4

Therefore, the opposite side to angle theta is 16.4 feet.

A board is 60 centimeters long Kelly cut the board into two pieces with 14 centimeters longer than the other find the longer pie
Dahasolnce [82]

Answer:

44 cm

Step-by-step explanation:

So, it is asking what the bigger piece of the 60 cm board is. First you can divide it into two even pieces. That makes each piece 30 cm. but, it wants one of the two 14 cm bigger, right? So, now your going to add 14 cm to 30 cm, giving you 44 cm. But, if you do that then you will have to subtract 14 cm from the other board. That leaves you with the bigger board is 44 cm, and the smaller one is 16 cm.

Find the values of m and n<br> Need help, thank you!!!
Wewaii [24]

Answer:

m=45 degrees

n=15 degrees

Step-by-step explanation:

m=45 degrees because other 2 angles in it's triangle =90+45=135 degrees

180 degrees in any triangle so m=180-135=45 degrees.

m+n=60 degrees so n=60-45=15 degrees
